COMBINED BOOK AND INDEX.

SPECIFICATION forming part of Letters Patent No. 408,260, dated August6, 1889.

Application filed February 28, 1889. Serial No. 301,462. (No model.)

To all whom it may concern.-

Be it known that I, HENRY E. PRATT, of Lambertville, in the county ofHunterdon and State of New Jersey, have invented certain new and usefulImprovements in a Combined Book and Index and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will e11- able others skilled in the art to which it appertainsto make and use the same.

My invention relates to an improvement in a combined book and index.

The object is to provide an index which may be at all times accessiblefor purposes of reference, and in which the leaves may be turned withoutconflicting with the turned same time to so connect the index with thebook as to insure its permanent attachment thereto under any ordinaryusage during the life of the book.

A further object is to provide an index and its connection with a bookwhich shall be simple, convenient, and quite inexpensive, and which willadmit of the index being folded flatly between the cover and last leafof the book.

lVith these ends in view, myinvention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 shows the index and book bothopen, as in position for use; Fig. 2 is an end View showing the indexpartially folded, and Fig. 3 is an end View showing the index foldedwithin the book.

In the present case the index is shown in combination with what iscommonly known as the Chadwick copying-book; but its use is not limitedto this or any other specific construction, except so far as the coverof the book serves to form the means for connecting the index thereto.

A represents the body of the book or its leaves, and 13 represents thecover of the book. In the style of book herein illustrated the cover Bis canvas, rendered stiff at the front and back of the book by sheets ofpaper-board.

The cover B, either at the front or back free edge, in the presentinstance at the back, is extended away from the book a distance equal tothe width of the index, or a little more, and to the free edge of thecover so extended the back edge e of the index 0 is hinged. The extendedportion B of the cover has a flexible joint I) at the edge of the bookcover proper, and said extended portion is preferably stiffened by asuitable lining of thin paper-board. The joints at Z) and c arepreferably re-enforced by strips (Z of fabric glued on their innerfaces. The index 0 is provided with thin paperboard covers E and E, theformer stopping short at its free edge the width of the column ofinitial-letters of the index, while the latter projects underneath saidcolumn and protects the outer edges of the leaves against wear when thebook is open and its index extended as in use.

By the above construction the index may be folded within and adjacent toone of the covers of the book,with its index, or, rather, theinitial-letters of its index, at all times exposed, while the leaves ofthe index may be turned backwardly toward the free edge of the bookproper and the leaves of the book proper turned toward the index withoutin the least conflicting therewith. It will be further noted that theprolongation of the book-cover forms a cheap, neat, and durable meansfor the attachment of theindex, does away with the necessity of anyclumsy device or devices foreign to the material employed inmanufacturing the book, saves the shaping and attachment to the book ofan intern1ediate separable piece, and admits of a compact and neatclosure of the index and its connecting-piece within the cover of thebook proper.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a book having one of its covers extended toform a folding extension, of an index hinged at its back to the freeedge of the extension, substantially as set forth. u

2. The combination, with a book having its cover extended beyond theedge of the book, of an index having its back hinged to the free edge ofthe cover-extension and provided with a cover of less width than thesaid cover-extensio1'1, substantially as set forth.

3. In combination, a book, an index provided with a back and frontcover, the front cover being narrower than the back cover to expose acolumn of initial-letters, and a projecting portion of the book-coverconnecting the index With the book and forming flexible joints at thefront edge of the book and at the back edge of the index, whereby theindex may be folded Within the cover of the book With its column ofinitial-letters at all 10 times exposed, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.
